IIMIPROVEDl ANIMAL AND BIRD-TRAP.

TO`ALL WHOM IT MAY CONCERN:

Be it known that I, GREENVILLE CARTER SrAMrEn, of Pella, in the county of Marion, and State of Iowa, have invented a new and improved Self-Setting Animal and Bird-Trapg and I do hereby declare that the following is a full, clear, and exact description of 1the construction and operation of the same, vreference beinghad to the annexed drawings, (making a part of this specification,) in which- Figure-1 is an end elevation, `a portion of the Wall beipg broken away;`

' Figure 2 is anend'elevation, when set for birds.

Figure 3 is a cross-section. i

Figure is a detached sectional view, showing the adjustingapparatus.

This invention relates to that class of traps which are actuated by'springs, and which are provided with a movable part that, when the trap is sprung, pushes the animal into areceptacle provided for the purpose.

The invention consists in a new arrangement of said parts, and a new device for setting, springing, and adjustingthe same to different classes of animals and birds, and in making the receptacles detachable and removable, for the purposes hereinafter set forth. y v

In the drawings, A A represent the body of the trap, the part A being removable, and, when removed, leaving the form of the trap as seen in figs.. 2 and 3, Bris a wheel, arranged lengthwise of tbe trap A A', operated by a convolntespring, E, on one end, and provided at the other end witha ratchet, e, pawl, al, spring, a2, for keeping the pawl in contact with the `ratchetand key, aifor holding the pawl away from vthe ratchet, when required. i Y

The wheelB is provided with a set of radial plates, b Z2 I), attached lto it like spokes, and extending the whole: length of the caso AA. C is a platform under theV removable part A" of the case, andi) is an apartment 'or chamber under the ixed part A of said case. i The radial plates 6 b of the `wheel B are so arranged and adjusted that the wheel extends from the inner edge of the platform to the central partof the concave roof-ceiling over it, cutting oil` all communication between the chamber D and `the space under the part A of the case, when'the wheel is in the position shown in iigs. 1, 2, or 3. -The apartment D communicates with an attachable'andremovablebox, F, having a foraminated top, F', the' passagefbetwecn them having a trap-gate, f', which the animal can push open, in order to pass into the box F, but which will automatically close after him, andpcut oif his retur-n.

C is the bait-box, attached -to the platform' C, as sho-wn in Eg. 8, and provided with a'spur or hook, c', to hold the bait, and c is a catch or stop `projecting upward fromvth'e inner edge ofthe platform, in sucli'a manner that the radial plates of the wheel B ,come in contactwith it, and thereby the wheel is prevented from revolving.

i When a bird or 'animal comes upon the platform C, in quest ofthe bait in the loo-x C', -or for any other purpose, his weight is designed to presslthe stop c down, or otherwise move it, so 4that it will be disconnected from the radial platein contact with it, when the spring E will cause'the wheel to revolve on its axis withgreat force, and the radialsplate next in -rearof that one which had i been in contact with the stop c, sweeps down across the platform, and pushes vthe animal off of the platform into the chamber *Before the wheel can revolve any further, the stop c, relieved by the expulsion of the animal from the platform, rises and intercepts the radial plate,` the operation of4 which has jus't been described, and thus sets the trap again automatically.

The animal finding himself inthe dark chamber D, is prevented from returning to the platform, both by the force of the-spring and by the operation of the ratchet and pawl a a', and seeing light through' the paseugej', he immediately makes his exit intothe lindependent box F, which, when'suiiiciently full, can be detached andremoved forthe purpose of killing the game. v

Gr is a deep'water-tight box, corresponding usually in width to the trap, and Vof lany length that may bei preferred. When the box F has been filled with game, and it is desirable to empty it, I till lor partially ll the box G with water, and set the box F upon it. By inspecting iig. 1, it will be seen that the bottom 'of box F is composed of two'trap'doors,which'open downward, and are supported in the position shown inthe drawing referred to, by-.meansof pins or dowels passing through the edge of the end wall into the ends of the trap-doors..

The box F having been placed on the tank G, the operator removes the dowels, and the weight of the animal opens the trap-doors and precipitates him into the water below, in which he is drowned. The box F is made of the saine length as the tank G, and of the same or a li-ttle less width.

` In setting the trap for birds,the part A of the ease is removed, andf every alternate radial plate is also removed, vin order that the bird may freely approach` the platform C from any quarter. Previous to setting the trap for such game, 'a hole isdug in the ground, and the box G is insertedin it, as shown'in iig.` 3, the top of the box coming slightly belowtho surface of the, ground. The trap is then placed on t,in the position shown' in the drawing last referred to, the platform C coming exactly on a level with the surface. A removable sheetmetal bottom, lwhich formed the Hoor of the chamber D, is then withdrawn, and the trap is'baited and is ready-tol operate. The bird comes upon the platform, depresses it, and springs the trap, which sweeps her into the now bottomless chamber D, from which she falls into the box Gr.

All the parts which are iufdanger of being gnawed and injured or destroyed bythe entrappod animals, may be lined with sheet metal or other suitable material, to protect them. vThe means which I preferably employ for adjusting the trap to game' of different sizes, and for facilitating the springing of the trap, may be described as follows, being clearly represented in iig. 4

f The platform-is pivoted along the edge opposite to the stop c, and its inner edge rises and falls, the stop c being a simple knob or pin ,projecting up from the edge of the platform. The inner edge of the platform rests upon a lever, M, provided with a friction-roller, r, and weight, m., by whichthe platform may be adjusted so as to be depressed, and the trap sprung more or less easily. When the weight is adjusted at the end of' the long arm of the lever, an animal of considerable size might pass over the platform without springing it, but whe'n placedvnear the fulcrum, or entirelyv removed, a mouse or small bird would at once spring the trap. The bai`t-4 hook c passes through ,thebottom or' side of the bait-box, and is fixed to a lever, N, or may be an extension of down, and insure his being caught.

the lever N. The latter is pivoted near-its centre to a block, O, belonging to the frame of` the trap, and independent of the platform C, and the other end of the lever is bent up towards the platform, and passes loosely through a staple in it, as seen at n) The effect of this arrangement will be that when the animal or bird is not suliciently heavy to spring the platform by this weight,he will, by pulling upon the bait, drawthe platform IAspring, s, may, if desired, be employed'to counterbalanee the weight of the platform, and may bermfade adjustable, so as to bear upthe platform with any required degree of force. t t are hooks-er hasps, and t t dwels, by which the box F isheld in place when in use, as shown in iig. 1. u is a hasp, by which the part A is secured in position.

l Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

i 1. The combination and arrangement of the fixed part A, and removable half, A', of the case or shell of the trap, with the wheel B and platform C, as and for the pprposes set forth.

- 2. The box E, when eonstructed'with foraminous top, trap-door bottom,.and `trap-guardf, and used in connection with the chamber D, in which the .animal is caught, and the bcjx G, in which he is drowned, in the manner' and for the purposes set forth. Y l

. 3. The employment of the underground box G, in connection with the bottomless chamber D,.and vfor the purposes set forth.`

' 4. The combination of thel platform C and baithooli c', with the lever N and beam O, as and for the purpose set forth. u

. 5. Theeombinationof-the platform C and weighted lever M, substantially as and for v the purpose set forth.
